Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | Vout | power_out | Regulated +5 V output (4.75-5.25 V over line/load). Supplies up to 100 mA. A 0.1 µF ceramic bypass capacitor to GND is recommended close to the pin for stability and transient response. |+| 2 | GND | power_in | Ground / common return for both input and output. On SOT-89 this pin is electrically and thermally tied to the large center tab used as the primary heat-sinking pad. |+| 3 | Vin | power_in | Unregulated DC input, typically 7-20 V for 5 V version (absolute max 30 V for Vo=5-9V parts). Dropout ~1.7 V. A 0.33 µF bypass capacitor to GND close to the pin is recommended when the regulator is far from the power source's filter capacitor. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | LRC |+| Package | SOT-89-3 |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++- `LR78L05A`+- `LR78L05ALR78L05B`++## CAD (KiCad official)++- Symbol: `LR78L05A`+- Footprint: `Package_TO_SOT_SMD:SOT-89-3`+- 3D model: SOT-89-3 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [LRC datasheet](docs/lr78l05a-datasheet.pdf) (6 pp, sha256 `a49a118b686fea89`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
